WebApr 10, 2024 · The Global Universal Hardness Testers Market refers to the market for the equipment used to test the hardness of various materials, including metals, plastics, ceramics, and composites, among others. WebMar 9, 2006 · Hardness is a measure of a material’s resistance to being scratched or dented and is measured using various experimental techniques, including the Vicker’s and Knoop tests. However, the values obtained often vary depending on the testing method — the Knoop diamond, for example, is sharper than the Vicker’s and gives a lower hardness.
